Google Authenticator is a mobile app that generates codes for two-factor authentication.

The only way someone can access your email, documents, or photos is by obtaining a code on your mobile device.

Pros

“This 2FA works seamlessly with our Network either with the use of a mobile device app, hardware token or even a code over a landline phone.”

Glen G.

Systems Operator

“It provides you with an additional layer of security and helps you prevent data breaches by providing strong user and device authentication.”

Vishnu Y.

Warehouse Executive

“We were asked to implement MFA for cisco anyconnect and we found DUO could do this job as cisco did not have their own solution for MFA.”

Diwakar D.

IT Manager

Pros

“I also like that a simple progress circle displays next to all of the logins you have saved in the app so you can clearly see how much time you have until the currently displayed set of codes resets.”

Stephanie P.

American accent coach

“From using it as a student to using it on my workplace, it has saved me a lot of time many times when I have to log into microsoft products.”

Aroob A.

Web Developer

“It also doesn’t have things like multi‑device sync or a built‑in lock, which would make it feel more modern.”

Meegan W.

Educator

Cons

“setting up a new device was challenging, for example if you did not have your phone with you bypassing the authentication with another device was not easy.”

sydney g.

Associate

“Console can be a bit difficult to navigate through when looking at applications/policies.”

Tyrek R.

IT network security analyst

“One of the problems is that sometimes, even with choosing the remember for 30 days option, I have to enter the passcode on my phone every time that I want to enter to my accounts.”

Leila S.

Research Scientist

Cons

“Even now, the export process feels a little clunky and not as smooth as other apps. If you forget to transfer your codes, you can get locked out of accounts fast.”

Meegan W.

Educator

“Sometimes the authenticator code will change in the middle of entering it and it will not accept the code and I will have to reenter the new code.”

Sherron S.

Case Manager

“For a long time, there was no backup at all, so losing your phone meant a full‑on panic.”
